[frs-287] Instance Manager reports “Could not update web descriptor”


Customers attempting to add an instance of FusionReactor using the FusionReactor Administration Manager (FRAM) Instance Manager receive a dialog box with the following text.

Could not update web descriptor /path/to/descriptor/default-web.xml.

Clicking "Skip" or the close icon is the only available action. The instance is not added.


We have tracked this issue to a problem when the J2EE server's runtime user is different to that of FusionReactor. This occurs usually when customers have locked down the J2EE server by changing its runtime user in Windows Services (for Windows) or by installing it as a non-root account in Linux or other Unix.

Because the web descriptor is owned by another user, FusionReactor is unable to access it to add a <filter> element. The dialogue box gives the full path to the file whose edit failed.


We have developed a procedure to allow FusionReactor to coexist with J2EE servers with differing runtime users. It is part of FusionReactor's online user manual, and can be found at the following URL:
